West Coast Airlines Flight 956 was a scheduled commercial flight which crashed on October 1, 1966, approximately 5.5 miles (8.9 km) south of Wemme, Oregon, United States. Thirteen passengers and five crew members were aboard, and there were no survivors. The aircraft was destroyed by the impact and subsequent fire. The probable cause of the accident was "the descent of the aircraft below its clearance limit and below that of surrounding obstructing terrain, but the Board was unable to determine the cause of such descent." This accident was the first loss of a Douglas DC-9.
